In bad Weather the side scuttles for the crews quarters and cabins whichare located on decks that are not at a high level, have to be keptclosed, so the airin the cabins in question soon becomes bad.

Now there are already inuse ships side scuttles with ventilating deviceswhereina casing is arrangedover the glass holder. Through this casingthe air fromoutside can enter the interior of the ship, and float valvesare provided in the casing, and upon the Water rising right above thelevel of the Window, prevent the Water from entering; the interior ofthe ship. Such side scuttles, on account of tlieease's being fitted upwith float valves of comparativelylarge diameters, are very lar e andcumbroiis, looknn'- attractiv and cannot be fitted in everywhere onaccount of Venetianb'linds and'flcurtains that may have to'be provided'.Since more over the float valves are arranged in the immediate neihborhood of the: aperture leading out of the; easing into the interiorof the shi'pit may happenthatsplashes reach the interior ofthe ship,particularly when may occur after some time owing to'rust or dirt.

ventilating device is provided, which can be fittedlip in any roomendisnot materially larger than an ordinary shipis side scuttle. A furtheradvantage of the side scuttle construction accorcling"to the inventionconsists in the fact that the ventilating device employed admitsofbeinigj adapted to side scuttles oi any shape, quite irrespeeti'velyof whether they are round or angular, andthet it is possible also to fitthe ventilating device into already existingside souttles.

The invention is' illustratedby s ay of example in the accompanyingdrawings.

B is a metalmembor is provided in the side scuttle as an annular passagein one of the metal members surrounding the Window pane, and closureele- Inents are arranged in thelower part of this member. In theconstructional.v example shown in Figure 1, such an annular passage D isprovidedin the metal member B immediateiy surrounding the glass disc Cand serving as the settingithereof, In the lower part of this passageare provided outwardly leading a'pertnresiE, end. as closure elementsfor these apertures balls F siipported in front 'of thenfarearranged ina' casing-G. Under. the resting" place of the individual closureelements are arranged ,outivh'rdlv leading-slots B in the casingiG,'whicli' referfably'run' nearly vertically as possible, asmay be seenfrom"Figure 2,150 that the jets ofwater entering here quickly bringtheclosure elements" on to their seats in the 'metal'niember" B'andhold"themfastthere.

In a" articularly advainta eous Christi-n0 tion'al for'm embodiedin'Figu'r'es '1 and 2', the

closure elements are arranged. in a special chaniber I,1or the casingforms apart of this "ohaniber'I', Whichislikevise constructi-fd as anannular chamber and arran ed in the metal member B surrounding the glasspane C. Upon the Water entering, this chamber I acts as an air vessel;andhe1ps,a fter the discharge of the Water, owingto the a ir coinpressedin it, to bring thec'losure elements bafck into the open position and toexpel I the Water thathas forced its Wayin. Inthe 7 case of theconstructional example illustrated, th'e ea'fsi'ng' fort-he closureelements and the chamber I are formed by an annular member K, whichs'c're'ivsint'o thepart'B. Aring'L serves for holding'th glass plate C.

In the upper part of the air pessag'e Dis provided an apertiire Mjwhicheanbe shut O is a5; known; screen 01* deadlight com- "pletely'shntting'off the side sctittle. A i

In" the" constructional form according to lltl Figures 3 and 4 theannular passage D and the annular chamber I containing the closureelements are arranged with the slots H in a special metal member P,which is inserted into the metal member 13, which serves as aglass-holder. The member P is held fast in the member 13 by a ring Q,and the member P is divided in this case, for the insertion of the paneof glass C, preferably along a line B.

Also in the case of this constructional form, in the upper part of theships window, namely in the part P, is provided a slot S, which can beclosed at will by a sliding shutter T.

In the constructional form according to Figures 5 and 6 the annularpassage D and the annular chamber I are provided with the closureelements F and the slots Him the window-fastening frame or window case,which is connected with the ships wall and which for this purpose ispreferably formed of two parts, namely a part U and a part U, whichparts are pressed against one another with the interposition of apacking. Here again in the upper part of the ships side scuttle slots Vare provided, which can be closed by sliding shutters IV. Specialpassages X are provided, which open into a chamber Y, so that the Waterpassing out of the latter through the slots H into the annular chamber Ilifts the ballsF and is able to bring them on to their seats. In thecase of this special construction a draining of the chamber Y preferablytakes place into the interior of the ships hold, for example through adraining screw, tube or the like inserted at Z.

In the case of the constructional forms according to Figures 1 and 2, aswell as 5 and 6, the ventilating device is in operation even when thescreen or deadlight O is closed.

The ships side scuttle according to the invention is of course notlimited to side scuttles the glass-holders of which are opened but isalso possible in aconstruction in which the setting for the pane ofglass is rigidly connected with the frame secured to the ships hull.

\Vhat we claim is:

l. A ships side scuttle, consisting in combination of a frame connectedwith the ships hull, a pane of glass, metal members surrounding saidpane of glass between said pane of glass and the frame on the shipshull, said metal members being formed with air ducts therein, and withapertures on the inner side of the scuttle and in the upper part of themetallic members, and with apertures on the outside thereof, saidoutside apertures being connected by said air duets with the aperturesfirst mentioned, and closure elements in these metal members for closingthe apertures under the influence of the pressure of the water outsidethe side scuttle.

2. A shi )s side scuttle, consisting in combination o a frame connectedwith the ships hull, a pane of glass, metal members surrounding saidpane of glass, between said pane of glass and the frame on the shipshull, said metal members being formed with air ducts therein, and withapertures on the inner side of the scuttle and in the upper part of themetallic members, and with aper.- tures in the lower part thereof, saidlower apertures being connected by said air duets with the aperturesfirst mentioned, and closure elements in said metal members for closingthe lastmentioned apertures under the influence of the pressure of thewater outside the side scuttle.
